This invention relates broadly to clocks, and has more particularreference to means whereby wind power may be utilized to wind up theclock.

In accordance with the present invention, there is provided what may betermed a self winding clock, in that the invention consists in theprovision of a power transmission mechanism connected to the clock forutilizing wind power to wind up the spring motor of the clock.

19 The invention together with its numerous objects and advantages willbe best understood from a study of the following description, taken inconnection with the accompanying drawings wherein:

Figure 1 is a front elevational view of the device.

Figure 2 is a top plan view thereof.

Figure 3 is a fragmentary rear elevational view thereof, with the rearcover plate of the sign board removed,

Figure 4 is a transverse sectional elevational view,

Figure 5 is a fragmentary sectional elevational view through a portionof the spring motor, and

25,; Figure 6 is a plan view of a combined gear wheel and ratchetforming part of the invention.

Referring more in detail to the drawings it will be seen that inventioncomprehends the provision of a base having a standard 6 risingtherefrom,

and rotatably mounted on the standard is what may be termed the signboard designated generally by the reference character 7.

The sign board comprises upper and lower frame members 8, 9, end framemembers 10, and

5;; front and rear plates 11, 12 suitably secured to the frame members8, 9 and 10.

The upper portion of the standard 6 extends through a bushing 13provided in the bottom frame member 9, and on its upper end the standard6 is provided with a bearing part 14. Connecting intermediate portionsof the frame bars 8 and 9 are relatively spaced bars 15 which in turnareconnected by a cross bar 16. The cross bar 16 has suitably mountedtherein a bearing g5: part 14a coacting with the coacting part 14 asshown in Figure 3. Thus it will be seen that the signboard '7 is mountedfor rotation on the standard 6.

Supported between the upper ends of the bars 15 is a plate 17 on whichis suitably mounted a clock 18, and in this connection it will be seenthat the front sign board plate 11 is provided with an aperture 11a foraccommodating the front or face portion of the clock. For driving theclock 18 there is provided a conventional spring motor designatedgenerally by the refer ence character 19, and the same includes a shaft20 about which the spring motor is properly disposed, and said motor asshown in Figure 5 is provided with a hub or sleeve 21 mounted on theshaft 20 for rotation relative thereto. A gear 22 is slidably mountedand on one end of the shaft 20 and the hub of the gear 22 has a ratchetface 23 cooperating with a similar ratchet clutch on one end of thesleeve or hub 21 for transmitting power from the gear 22 to the hub. Aspring 24 is arranged on one end of the shaft 20 and one end of thespring bears against the gear 22, while the other end of the springbears against a head 20a. provided on said shaft 20; spring 24 thus 7serving to normally retain the gear 22 and clutch to the hub or sleeve21.

For driving the gear 22 there is provided a suitable reduction gearingdesignated generally by the reference character 25 and mounted on 7 theplate 17. The transmission gearing 25 includes also a relatively smallpinion gear 25a mounted on a shaft suitably journalled in a bracket 26fixed to the plate 17.

Connected with the shaft on which the pinion gear 25 is secured, is aspring 27 which has an end thereof secured in a plug 28 fixedly arrangedin the upper end of the standard 6.

From the above it will be apparent, that as the signboard '7 rotatesabout the longitudinal axis of the standard 6, the end of the spring 27is anchored to the standard 6, a rotation of the shaft on the piniongear 25 will be effective and drive transmitted therefrom through thereduction gearing to the hub 24 resulting in a so winding of the springmotor. Thus it will be seen that I have provided a device which will befound especially useful as an advertising clock for jewelers, and onewhich will not require a great deal of attention, and yet at the sametime will be maintained in a suitably wound condition.

It will be noted, either or both plates 12 may be utilized forsupporting signs or other advertising data as suggested in Figure 1 andthere is preferably also provided at each end of the signboard a windvane 29, the wind vane 29 extending in an opposite direction asindicated in Figure 2.

Even though I have herein shown and described the preferred embodimentof the invention, it is to be understood that the same. is susceptibleof further changes, modifications and improvements coming within thescope of the appended claims.

Having thus described my invention, what I claim as new is:

1. In a device of the character described, a standard, a support mountedon the standard for rotation relative thereto, a clock carried by saidsupport, and power transmission means connected with the clock and withsaid standard for utilizing rotative movement of the support to wind theclock.

2. In combination, a standard, a support rotatably mounted on saidstandard, a clock carried by said support, a spring motor for saidclock, a shaft mounted on said support and having its axis disposed atright angles to the axis of said standard, transmission gearingconnecting said shaft with said spring motor, and a spring secured atone end to said shaft, and at its other end to said standard.

3. A device for utilizing wind power for winding clocks comprising arotatable member, a fixed member about which the first named member isrotatable, a clock carried by the rotatable mem her and including amotor, and power transmission means connecting the motor of said clockwith said fixed member.

4. A device for utilizing wind power comprising a supporting structure,a member rotatably mounted on said supporting structure, a spring motorcarried by said rotatable member, and including a shaft, a hub on saidshaft, and a spring having an end anchored to said hub, a gear on saidshaft, hub means connecting said gear with the hub, and driving meansfor said gear including a spring having an end anchored to thesupporting structure.
